Description
Sum nonnegative concurrentDemand for demand.
Capacity accounting compares available supply with commitments, reservations, or demand. Negative residuals can expose overload while zero capacity requires a distinct undefined utilization state.
Sum nonnegative concurrentDemand for demand.
When to use this tool
Use Task Overlap Capacity Excess when you need a transparent resource or workload capacity term.
How to use the tool and how it works
- Enter concurrentDemand, capacity. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read demand, excess, spare. Use the output convention below.
Sum nonnegative concurrentDemand for demand. Return zero-floored demand minus capacity as excess and capacity minus demand as spare.1
| Input field | Meaning and units | Accepted input |

| concurrentDemand | Concurrent Demand | Required. Array of finite number; minimum 0; maximum items 256. |
| capacity | Capacity | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| demand | Demand | Required. Finite number. |
| excess | Excess | Required. Finite number. |
| spare | Spare | Required. Finite number. |

}Limitations and assumptions
- This is an aggregate snapshot without scheduling, resource compatibility, or uncertainty analysis.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Validate calendars, skill constraints, and concurrent demand with the actual resource plan.

Divide demand by capacity only when capacity is positive; otherwise return utilization zero and defined false.
